The United States’ payment processing industry continues to expand at a strong pace. According to recent industry projections, the global payment processor market is expected to grow from approximately $63.9 billion in 2025 to $71.2 billion in 2026, with continued double-digit growth projected through the end of the decade. In North America alone, the broader payments market was forecast to reach $426.7 billion in 2025 and $471 billion in 2026, reflecting sustained demand for payment processing.
This presents a massive opportunity to build a profitable book of business by helping merchants upgrade how they accept and manage payments. As more businesses look for better rates, smarter reporting, and seamless omnichannel tools, strong sales professionals can step in as trusted advisors rather than just vendors.
TL;DR
- A merchant services provider facilitates the point-of-sale system, payment gateway, and other components needed for credit card processing services.
- To sell merchant services, you must decide if a registered ISO or independent sales agent structure is a better choice.

What are merchant services?
The term “merchant services” includes multiple functions pertaining to merchants’ payment processing operations. For starters, the merchant services provider facilitates the point-of-sale system, payment gateway (for ecommerce transactions), and other components needed for credit card processing services.
The merchant services company furnishes all hardware, software, and materials to support these operations. Equally important, the provider offers ongoing customer support to its business owners.
Stax, for example, provides multiple solutions to enable merchants to accept various payment methods across different channels (e.g., in-store, online, on mobile, etc). In addition to providing payment processing software, Stax also offers several hardware options based on the merchant’s needs.
A merchant services sales rep may serve retailers, restaurant owners, and convenience store owners, among others. Mobile plumbers, mobile auto detailers, and professional service providers like law firms also have payment processing needs.
How the payment processing business model works
If you’re selling merchant services, you need a clear understanding of how payment processing actually works. The merchant services industry involves multiple players, including acquiring banks, payment processors, and merchant services providers. Together, they enable businesses to accept credit card payments, debit card payments, and online payments.
When a business processes a transaction, several entities work behind the scenes to approve, route, and fund that payment. Understanding this structure helps you explain pricing, position payment solutions effectively, and build trust with prospective clients.
The role of the acquiring bank
The acquiring bank is the financial institution that sponsors merchant accounts. Before a small business owner can accept payments, they must go through an application process and be approved by an acquiring bank.
The acquiring bank assumes risk. It underwrites the business, monitors chargebacks, and ensures compliance with card network rules. If a merchant operates in a high-risk category, higher costs or reserve requirements may apply. Without the acquiring bank, businesses cannot process credit and debit cards.
Payment processors vs. merchant services providers
A payment processor handles the technical side of processing transactions. It routes transaction data between the point-of-sale system, payment gateways, card networks, and issuing banks.
A merchant services provider bundles those payment processing services into a complete solution. A merchant services company may offer POS systems, credit card processing services, debit card processing, payment gateways for ecommerce, and ongoing support.
In many cases, independent sales organizations or sales agents market these services on behalf of a larger payment processing company or acquiring bank.
Where processing fees come from
Every processing fee typically includes interchange, card network assessments, and a markup. Interchange goes to the issuing bank. Assessments go to the card networks. The markup goes to the merchant services provider or payment processor.
Fees vary based on transaction type, industry risk, and volume. When selling merchant services, breaking down these costs clearly helps potential customers understand what they’re paying and why.
How residual income is earned in merchant services sales
Merchant services sales generate residual income because revenue is tied to ongoing transaction volume. Each time a merchant processes credit card payments or debit card transactions, a small margin is earned.
As you build a portfolio of merchant accounts, that recurring revenue grows. With strong industry knowledge, competitive pricing, and excellent customer service, you can create a sustainable payment processing business that produces long-term income.
How to sell merchant services
First and foremost, you must build a solid foundation for your merchant services sales business. Determine your business structure with guidance from your sales agent program. If necessary, obtain assistance from a certified public accountant familiar with sales-related business needs.
Is a registered ISO or independent agent the right choice?
Decide if a registered ISO or an independent agent structure is a better choice. A registered ISO must be accepted by a major payment processor and approved by the card brands. An independent agent works under the sponsorship of a registered ISO but does not hold their own card brand registration.
All that being said, here are some tips to position yourself for merchant services sales success:
Set a concrete sales goal
As with other sales jobs, setting a goal is the first step to achieving it. Determine how many clients you want to obtain every month and how much income you want to make. Keep this goal at the forefront of everything you do.
Design a client-getting strategy
If you meet your cold calling goals but don’t have a sales strategy, you won’t get the desired results. Before visiting a single prospect, develop a concrete sales strategy. Use your sales agent program and proven sales principles for guidance.
Create an effective sales pitch
Most business owners have seen their share of halfhearted sales pitches. The salesperson has obviously not done their homework and, therefore, knows very little about the business’s real-world needs. In such cases, the sales rep delivers a prepackaged sales pitch and crosses their fingers that it works.
Instead, build an effective sales pitch that focuses on cost transparency. Show them exactly how much they currently pay in hidden fees and how simplified pricing models (like Stax Connect’s) deliver predictable savings and eliminate confusing markups.
Consistently deliver real value
Every successful sales transaction is based on value. In return for the prospect’s commitment, they want a targeted solution that helps to grow their business. Deliver this value by showing that your solution is leaps and bounds above competitors’ offerings. Show them that you’re committed to supporting their success.
What are some tips for selling merchant services the right way?
Before selling merchant services, a sales rep should educate themselves about the payments industry’s operation. Becoming familiar with current merchant services trends and new technologies is also important.
Learn about the credit card processing industry
Begin building your credit card processing industry knowledge base. First, gain information about the role of a credit card processor. This entity handles the actual transaction processing. The merchant services provider is the business (often an ISO) that bundles the processor’s services with hardware, support, and sales.
Each merchant services provider chooses its pricing structure. Within this structure, the provider details the credit card processing fees and rates. Agents must understand and compare the three main pricing models: interchange plus, tiered, and the modern flat-rate subscription model.
Companies that operate in a high-risk industry—or those with high chargeback ratios or poor business credit—will pay more for that increased risk through higher reserve requirements and processing rates. In certain cases, the provider’s pricing structure may include a credit card surcharge or non-cash adjustment component (NCA).
Finally, learn how a full-featured POS system can help to be the central operational and data hub for a business’s growth, integrating inventory, sales, and customer data. Handheld POS systems and card readers are key to processing sales for companies in diverse industries. This hardware, along with payment gateway software for ecommerce businesses, facilitates smooth credit card and debit card sales.
Build your knowledge of the company’s offerings
Establish a competitive advantage by taking the time to understand your company’s products and services. Immerse yourself in the provided sales materials so you can explain why your company provides the best merchant services. Over time, your hard work will pay off. You’ll be able to easily relate the company’s unique selling proposition to new business prospects.
Listen closely to each customer’s needs
To excel in merchant services sales, a sales agent must actively cultivate the art of listening, which helps them learn about the business owner’s pain points and unmet needs. If the prospect is dissatisfied with their current payment processor, the sales agent should find out why.
Maybe the company’s merchant services package doesn’t correspond to the business’s needs. Maybe their current processing company sales rep delivered a packaged sales pitch rather than taking time to really engage the business owner in conversation. And finally, the sales rep didn’t bother to follow up after the sale.
Offer flexible payment options
In the merchant services industry, a “one size fits all” payment approach excludes many potential prospects. Businesses have varied funding streams and cash flow cycles. By providing multiple payment solutions, you’re more likely to obtain a “yes” from your sales interactions.
Consistently invest in referrals
A steady stream of referrals will fast-track your merchant services career. To set the stage for referral business, provide superb service satisfied clients will rave about. They’ll likely tell their friends, family, and business colleagues. Chances are that they’ll also spread the news on social media.
Develop a strategy to obtain referrals from happy clients. Follow up on all interactions, and over time, you’ll build a regular flow of referrals that drives your business’s expansion.
Obtain ongoing sales training
Every merchant services company includes targeted sales training in its agent program. This carefully designed instruction will provide a good foundation for your work with prospects and customers.
To obtain an extra edge, read classic sales training books that have withstood the test of time. Delve into biographies of highly successful salespeople. Listen to podcasts featuring interviews with sales industry leaders. Take every opportunity to excel at your craft.
